Value-at-Risk

Measure and quantify various types of risk exposure with value-at-risk

Value-at-risk (VaR) is the risk measure that estimates the maximum potential loss of risk exposure given confidence level and time period.

In other words, there is 1% chance that the potential loss over a one-day period will be greater than $10 million.

Value-at-risk is popularly used not only in risk reporting, but also in multiple phases of the risk management life cycle, including:
